Control of Processes with Inverse Response and Long-Dead-time: An Experimental Evaluation

This study uses the TCLab control education system to replicate a system featuring a dominant time delay and an inverse response. The original configuration of the TCLab system follows a first-order plus dead-time model, which lacks the inverse response element. Two additional transfer functions were incorporated into the TCLab setup to emulate the desired system characteristics. The performance of two distinct control strategies, the Iinoya compensator and the PI controller, was thoroughly evaluated through a series of tests. Multiple performance indices were used to measure the effectiveness of these control schemes. The results consistently indicated that the Iinoya compensator outperformed the PI controller on all the performance indices evaluated. The results suggest that the Iinoya compensator holds substantial promise as a control approach for processes characterized by significant time delays and inverse responses.
